Answer:
c- Solid, liquid, gas
Step-by-step explanation:
The inter molecular gap in solid is the lowest so sound travels fastest through solids
The inter-molecular gap in liquids is higher than solids so sound travels slower when compared though solids.
The inter-molecular gap in gasses is the highest among the three states of matter which makes sound travel through it the slowest.
So, the order from fastest to slowest will be Solid, liquid, gas
